iPhone apps must also run on iPad without modification, at iPhone resolution, and at 2X iPhone 3GS resolution

I tried running my app on the iPad simulator. I thought it would be centered in the iPad screen but it was instead in the upper left hand corner. The size that of an iPhone app. Is that typical.

My questions:

a.) Why would the main view be located in the upper left hand corner?

b.) Is there anything special I need to do to an iPhone app to make it pass the above rule. At this time, we are not ready to release an iPad version.

That is strange indeed. Did you try testing it on an iPad device?
